White nodules in War Coral?

[overclockwise]

I've had this war coral for about a month now and it's been doing fantastic during that time. Tonight, I got home and I noticed that it got a bunch of white nodules on it. The rest of the coral seems to be fine and all my other corals look okay - anyone know what these are?

If it's night time it's probably a feeding response

I took a look at it this morning and it seems like new tissue grew over it. I'm thinking it might be bare skeleton that it calcified before growing tissue over it. It's odd that it was so pronounced, though.

they look like bubbles with the white part being the reflection of your lights.
